MST – DUAL 2164 VCA

The MST Dual 2164 VCA is a precision AC (audio) & DC (gate triggers or control voltage) Voltage Controlled Amplifier in 6HP. Each channel has a linear or exponential response switch, the exponential resulting in a “poppier” response. Adjustable output level and bleed if you want to mix in your unaffected source audio. Butters your toast all the way to the edge.

Hey one of my VCA chips blew so i replaced it (on first try of the module). it might have been put in bssackwards but i replaced the chip and it still doesn’t work, the diodes looked a bit weird so i replaced those, still nothing… I live in Portland so if i walk into your storefront will you guys check it out?

I’ve just purchased and built this module… However, it generates sound (~ 50% power) when the level is fullly CW, bleed is fully CCW and no CV input is present. Is there an adjustment for this? If not, where would I need to look on the module to troubleshoot?
